What is the record high temperature in Pittsburgh?

The all-time record high in Pittsburgh is 102°F, recorded on July 14, 1936. Records are drawn from the nearest long-term weather station's full daily history, so this is the hottest single day the station has ever logged — not a typical summer peak.

What is the coldest day ever recorded in Pittsburgh?

Pittsburgh's coldest day on record bottomed out at -16°F, set on January 23, 1936. Like the record high, it comes from the station's complete daily record, so it captures the most extreme cold the area has recorded rather than an average winter low.

Is it normal to be this hot in Pittsburgh?

It depends on how far above Pittsburgh's normal a given day runs. A typical year here averages a daily high near 61°F; the all-time record of 102°F (set 1936) sits about 41°F above that. The anomaly readout at the top of this page compares the current temperature against this month's normal high, so you can see exactly how unusual today is rather than guessing.

When did Pittsburgh set its temperature records?

Pittsburgh's record high of 102°F was set in 1936 (July 14, 1936), and its record low of -16°F in 1936 (January 23, 1936). Both are pulled from the station's complete daily record going back to 1935, so they reflect the true extremes rather than a recent or partial sample.

Has Pittsburgh been getting hotter?

Yes — Pittsburgh's annual mean temperature has trended about 0.2°F warmer since 1935, in line with the long-term warming seen across nearly every US city. That gradual shift in the average is separate from the all-time records above, which mark the single most extreme days rather than the trend, but a warming baseline is part of why recent years more often brush up against the record-high end.

How extreme Pittsburgh’s weather gets

Pittsburgh’s weather is usually mild by its own standards — a typical year averages a daily high near 61°F, and the normal high for June runs about 79°F. The records sit well outside that everyday range. The hottest day on record reached 102°F in 1936 — roughly 41°F above a typical year’s average high, the kind of gap that turns an ordinary summer into a genuine heat event.

At the other end, Pittsburgh has bottomed out at -16°F (1936). Together the two extremes span 118°F — the full width of what this place’s weather has done across the station’s daily record back to 1935. Those edges are exactly why the anomaly readout at the top of this page is worth a glance: it shows where today falls between the normal and the record, so a hot afternoon can be judged against the real history rather than a hunch. A reading a few degrees over the June normal is ordinary; one pushing toward the 102°F record is the rare event the record marks.
